Cart before the horse? My daughter was visiting so she tried to teach me how to upload a video.
The tower is made of 6 slabs of cedar boards rounded on a table saw. Circuits are on 2 R-S prototype boards
The solar panel is on roof of keepers house with battery & circuits inside.

Nice! did you use the same circuit that @torpedochief used?
EDIT: never mind... I've just noticed that you posted the circuits in post #3, and they're nothing like the ones I mentioned. But the video definitely shows they work quite well. Congrats!
